IPTRUDUGTION Q ACCENTED CHARACTERS 1N TYPOGRAPHICAL CCIMPOSING ANDCASTING MACHINES.

Application filed September 2, 1925, Serial No. 54,002, and in GreatBritain September 26, 1924.

This invention relates to the production of accented. characters intypographical composing and casting machines such as thoseknowncommercially under the trade mark Linotype. More particularly, the1nvention is concerned with an improved method of forming and utilizingaccents, which is especially advantageous in connection with slugs ortype-bars bearingcapital characters in large display faces. Thecharactors themselves occupy practically the full body width of suchslugs, and consequently the presence of an accented character in a linenecessitates the casting of: the slug in a mould having a body of largersize than that required for an unaccented slug, unless the slug isproduced with an overhang bearing the accent, in which case amodification of the slug-trimming mechanism must be made.

In carrying out the present invention the necessity for changes such asthose just referred to, are avoided by a method which involves theproduction oi a slug bearing accents alone, and afterwards associatingthe accent slug, or portions o't it, with a slug bearing the characters,which is cast in a mould ot the normal. body dimension appropriate tothe size of the face in use.

As is well known, in machines of: the kind to which the inventionrelates, the matrices, which are 'assen'ibled in line and presented tothe mould for thecasting of the slug, bear their characters in invertedposition, and are arranged for alignment at the bottom of the slug ascast with the bases of the characters presented towards the top oi theslug as cast. The accent matrices, which it is proposed to use for theproduction of an ac cont slug according to the present invention, diiierfrom the just-mentioned normal arrangement in that the accents thereonare not inverted and, although also arranged to align at the bottom ofthe slug as cast, have their bases presented towards the bottom oil? theslug as cast. Hence, the accents in such slug may he brought intocorrect relationship with the character slug irrespective oi the bodydimension of the mould in which the accent slug is cast, as the twoslugs are associated by inverting the accent slug and assembling it inthe forms against the top of the character slug.

In the accompanying drawings which are to be taken as part of thisspecification and read therewith Figure 1. is a perspective view of amatrix used in the casting, according to the pres ent invention, of anaccent-hearing slug;

Figure 2 is a perspective of a matrix used in the casting of acharacter-bearing slug complemental to that produced troma matrix suchas that shown in Figure 1;

Figure 3 is a view of a slug having accent faces produced from matricessuch as shown in Figure 1; a

Figure 4 a view similar to Figure 3, of a slug having character facesproduced from matrices such as shown in Figure 2, and

Figure 5 is an example of printing from the two slugs shown in Figures 3and 4:.

The matrix 1 shown in Figure 1 is one for producing a circumflex accent,while the matrix 2 shown in Figure 2 is for producing the character A.By comparing these two figures it will be seen that whereas charactermatrices 2 have their :tormative cavities 3 so disposed as to cast thecharacters 4-. in inverted position. on the slug 5 (Figure l) and arearranged to present the bases of the characters towards the top of saidslug as cast, which is the ordinary procedure, accent matrices l havetheiriiorinative cavities 6 arranged to cast the accents 7 011 the slug8 (Figure with their iicet presented towards the bottom of the slug ascast and of a body dimensioi'i not exceeding that of the slug itself.

It will thereiore be evident that whatever may be the body dimension ofa slug 8 or the mould cavity in which it is cast (and two difierentthicknesses of slug are indicated in Figure 3, one in full lines and theother in both full and dotted lines) the accents on said slug can alwaysbe brought into correct relationship with the respective characters t ona character-bearing slug 5, by inverting the accent-bearing slug andthereafter assembling; it in the torme with the feet of the accentsfacing towards the top of the slug 5, so that the conjunction of twoslugs such as those represented in Fig urcs and t would serve to producea line of accented display printing such as is shown in Figure 5.

Figures 3 and i show the slugs 5 and 8 in the positions in wh ch theyare cast in the mould. Froni an inspection of these figures it will beseen that whereas the matrices for producing the characters i areasseinliled in the orderin which said characters are to appear in print,itheimatriees,
